Abstract

The invention discloses a fixture convenient for punching, which comprises an upper cover, a lower cover, a body, short screws and long screws. Both the upper cover and the lower cover are provided with counter bores. The body is provided with an opening in the center, and the opening is the same as a workpiece in shape. Both the top and the bottom of the body are provided with threaded holes corresponding to the counter bores on the upper cover and the lower cover. The upper cover is provided with two through holes corresponding to positions, to be punched, on the workpiece. The upper cover is fixed to the body through the short screws on the counter bores of the upper cover. The lower cover is provided with a projection in the center, which is the same as the workpiece in shape. The projection is fixedly connected with the lower cover, and both sides of the projection are graduated. The projection is inserted into the opening. The lower cover is fixed to the body through the long screws on the counter bores of the lower cover. By means of the fixture convenient for punching, machining precision can be well guaranteed, and a plurality of workpieces can be machined simultaneously. The fixture is convenient in operation and highly practical.

Description

technical field [0001] The invention relates to a clamp, in particular to a clamp which is convenient for punching holes. Background technique [0002] Due to the development of production technology, the structure of machinery is also diverse, and the mechanical parts inside are even more structured. Mechanical parts are inseparable individual parts that make up machinery and machines, and are the basic unit of machinery. Now there is a semi-curved thin plate (such as image 3 Shown) need to be processed, mainly need to punch holes at both ends of the workpiece. Such workpieces belong to irregular workpieces, and the positions of the upper holes are also irregular, so it is very inconvenient to fix them. Existing methods generally use a pressure plate and a compression nut to fix the workpiece on the drilling machine, and then process it. Although this can be used to drill holes, the accuracy cannot be fully guaranteed by the compression nut alone. It is troublesome to pr...
